* bfd-in.h: Update <stdbool.h> check to only see if <stdbool.h> has
been included, not drag it in.

Fixes toolchain/16709, from Christian Limpach <chris@Pin.LU>.
(alpha_expand_unaligned_load, alpha_expand_unaligned_store):
Cast switch operand of size to int.
Fixes one 32-bit host cross-compile problem, but still doesn't work...
compare_addsi2_op0 & compare_addsi2_op1. From the comment I've just
inserted:
;; XXX RWE: The reload pass of GCC-2.95 makes a mess of these if one of the
;; arguments is, or is directly derived from, an eliminable register. In
;; that case reload will substitue into the PLUS and then canonicalize it
;; without regard to the the match_dup parts. Since these are rare, I've
;; disabled them for now, but they should be OK in 3.x (which manages the
;; substitution without canonicalization.
Fixes PRs port-arm/16424 and toolchain/16304.

correctly.
Enable -msoft-quad-float as the default moving forward. A complete build with
this compiler produces no errors and passes known regressions problems (awk,
etc).
XXX - -mhard-quad-float no longer will generate code correctly (internal
compiler problems). This is the case all the way to gcc-current so it's not
an easy fix at the moment but no one should be using hard quad math anyways.
If one doesn't subtract the stack bias back off %fp before attempting
to access variables stored relative to %fp the wrong address is picked up for
all locals and args. So, calls to the FRAME_LOCALS_ADDRESS or
FRAME_ARGS_ADDRESS macros need a function for sparc64 specific cases.
Provide a function to check for bias's addresses and fix them up.

This change will be documented in doc/HACKS.
set the C(arry) bit appropriately. All other leave it in an indeterminate
(to GCC) state. Mark that by setting CC_NO_OVERFLOW. Change vax.md emission
of branches that use the C bit to use OUTPUT_JUMP so that if CC_NO_OVERFLOW is
set, branches that would normally use the C bit use opcodes that don't use the
C bit (jgtru -> jneq && jlssu -> jeql). Delete the cmpdi pattern.
Define IN_SIGTRAMP() as nbsd_in_sigtramp(), a new function which knows
how to find the address of the signal trampoline at runtime, thus allowing
one gdb binary to work on all NetBSD/m68k machines.

gmon_write_raw_arc to write call graph records.
This makes the GMON_PTR_SIZE constant obsolete, however I have not
included the changes to the autoconf machinery that eliminate that
constant completely in order to minimize the changes here (they
will be picked up when we import Binutils 2.12 when it is released).

* config/mips/mips.h (FUNCTION_PROFILER): Deal with
the case where jal is expanded as a macro.
This is done by removing the .reorder/.noreorder, and moving the
call to _mcount to after the stack adjust, thereby letting the
assembler deal with the delay slot, etc.
This fixes profiling with libraries built -mabicalls (default on
NetBSD).
I can't believe how long this problem has been discussed-but-not-fixed
on the GCC mailing list...
* jump-format jumps: the target is in RB, so use the RB bits in
the insn, not the RA bits.
* branch-format displacements are 21 bits; extract all of them, and
sign-extend correctly.
* For conditional branches, we need to determine whether or not
the branch is actually taken.

the patch I posted to tech-toolchain@netbsd.org as a workaround for the
GOT bug whereby the callee-saved register %a5 can be trashed in certain
optimised -fPIC functions.
This may yet need to be fixed a different way, pending input from
Andreas Schwab on his change in revison 1.33 of this file in the
FSF source...
In the meantime, I've built and installed several NetBSD shared libraries
(including libc) with my change and found no problems.

with the change, since it was apparently made to appease one
particular OS, even though previous binutils releases had been
made with ENTRY=__start, and have brought it up on

Don't call reg_used_between_p if the insn from BL2 is after
the insn from BL.
This fixes a cc1 SEGV on sys/dev/scsipi/ch.c rev 1.48 under -O2 or -Os,
seen on m68k and vax.
* move the code that supplies the integer and FP registers into
separate functions, rather than duplicating the code for the
ptrace and core file cases.
* Use supply_register() rather than just copying directly into
the register array and calling registers_fetched(). This way,
only the registers actually supplied are marked as valid within
the debugger.
* Add support for SSE/SSE2 registers via the PT_{GET,SET}XMMREGS
ptrace(2) request.

the master GDB sources.)

minimal tweaks and cleanups by me (mainly: build bi-endian by default, add
NetBSD kcore support back).
and place it in i386nbsd-tdep.c (new file).
- Move solib.o from TDEPFILES to NATDEPFILES (solib.c requires target
headers, namely <link_elf.h>).
Fixes build of cross-gdb pointed at i386--netbsd target.
